ideally not requiring a terminal
No chance, sorry. Look at every Linux distro in existence and you'll find the terminal pinned in the Dock. Learning to use it is just part of The Linux Experience.
ideally doesn't require a password for every input
You can enable autologin, but in my experience this just means you have to enter your password in every time you open a new app. You can look into Howdy. Basically the Linux equivalent of Windows Hello. But this will require terminal to configure as well. And most likely still wont work because biometric hardware is rarely compatible with Linux.
